UNDERSTANDING OTHER WORLDS
Could there be life on exoplanets?
It remains an open scientific question. A promising planet is a target for study, not a confirmed inhabited world.
Conditions and evidence
Water, energy and suitable chemistry are useful starting points. Surface conditions on most exoplanets remain unknown. A habitable-zone orbit is only part of the picture.
Atmospheres under scrutiny
Scientists search for combinations of gases and other clues, while testing non-biological explanations. No single striking headline substitutes for repeated evidence.
A careful approach
This atlas does not label a world as inhabited or safe for humans. It explains what measurements support and where uncertainty remains.
